Another way to get info is to power on the scanner and plug it in, then `modprobe -r` the appropriate kernel module(s) and then modprobe them while doing `tail -F /var/log/messages`. The kernel (udev) will create the appropriate /dev entries upon successful modprobe. In order for your user to be registered as a member of a group you have to log completely out (including your X session) and back in. You can verify your group memberships with the groups command. Judging from what you've said I bet it was merely an issue of adding your user to the scanner or usb group. My experience with usb scanners is they generally just work whereas when I start up my SCSI scanner I always have to remodprobe the kernel drivers and then `chown :scanner /dev/sg? && chmod 0770 /dev/sg?`, but there's probably a better (right) way to do that. :-) Justin
